My fellow hard surface gurus and I are getting more and more calls from cleaners who are experiencing all sorts of strange issues while cleaning modern porcelain tile.
Odd streaks or splotchieness or water marking showing up when dried
Etching from acids
SCRATCHING...
Mark Saiger did some recent testing on a selection of tiles from Home Depot and came up with some great observations:
DONT LET YOUR HIGH PH CLEANER DRY ON THE TILE BEFORE YOU RINSE IT
Test your acids, if you have to use them on the grout.
Run an acid rinse (pH 4-4.5) at all times
Some tiles appear to have coatings on them that are not mush more than a layer of VCT wax.
Factory applied slip resistant coatings/treatments are the culprit.
Teflon wand Glides can indeed scratch Porcelain.
Stay under 10pH if possible.
Hers is what a dried high pH pre-spray can cause, which buffing with an acid cleaner fixed. (recleaning would not...)
